Precision Stainless Steel Ball Bearings
Open
Shielded
Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.
Open bearings dissipate heat more efficiently than shielded bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
